comment Is the traditional free-body diagram invalid in situations in which equal forces produce unequal powers?
@SaurabhRaje The FBD is drawn for the craft as a whole has a force on the propeller and a frictional force on the ground. The propeller's FBD consists of a input force from the wind and then some sort of output force on the wheels such that the wheels receives less power than the wind put in.

@SaurabhRaje I think the frame is still considered inertial, but different parts of the body pass through different distances in their respective media.

comment Limitations on the choice of axis of rotation regarding rolling wheels
I mean that forces are drawn on the diagram (such as normal force, gravity, friction) and the directions state to rank the forces with respect to the torques they give.

comment Is there a more clever way to apply the cross product of two vectors to magnetism?
@zephyr I guess I thought that there might be a quicker way than the jumble of variables wikipedia had. I guess the jumble is inherent in matrices. (I am pre-calculus).

Thanks for the great answer.
